STUDIES IN MARYLAND GEOLOGY�IN COMMEMORATION OF THE CENTENNIAL

A hand-written report illustrated with photographs, maps and drawings, entitled The Patapsco Project, which documents the Baltimore City’s Department of Public Works investigation of water and water power rights – essentially, the active, inactive, and ruined mills and dams – along the Patapsco River and its tributaries in Maryland between 1932 and 1933. This historic document is now available as a free download in PDF format through the Maryland State Archives (http://msa.maryland.gov/).

GEOLOGY OF THE HARPERS FERRY QUADRANGLE, VIRGINIA,
MARYLAND, AND WEST VIRIGINA

Series of 102 digital orthophoto quadrangles and 8 digital orthophoto quarter-quadrangles
covering the Chesapeake Bay area of Maryland, including the tidal reaches of the major bay
tributaries. The source documents (black and white Kodak paper prints) were produced by the
U.S. Geological Survey from 1988-1989 National Aerial Photography Program (NAPP) photography
and comply with National Map Accuracy Standards at 1:24,000. Rasters were produced by scanning
the paper prints at 1000 dots/inch (dpi) and down-sampling to 250 dpi (ground pixel size =
8X8 ft.). Color depth is 8 bits (256 gray levels). Map collars were excluded from the scan;
place names, neat lines and Universal Transverse Mercator (UTM) grid lines are an inextricable
part of the image. Files are approximately 30 megabytes in size and are available on CD-ROM,
erasable optical disk, or, for small orders ( 5 quads), via the Internet. Native format is
MicroImages .RVC; .TIFF format is also available. Detailed documentation, compliant with federal
metadata standards, is transferred in ASCII format with the files. Purchasers are required
to sign a licensing agreement.

Contact Ms. Katie Offerman at (410) 554-5543 or katherine.offerman@maryland.gov
. Do not direct inquiries pertaining to digital products to the MGS publications
office.

Five other maps for this atlas are available only for inspection at MGS: 4. Overburden;
5. Land modification; 6. Depth to the water table and location of wells, springs, and
test holes; 7. Availability of ground water; 8. Constraints on installation of septic
systems. Cleaves, E.T. and Otton, E.G., 1979.

* Please see the Geologic Quadrangle maps on CD-ROM page for more information about this series. Geologic Quadrangle maps on CD-ROM contain a copy of the map in Adobe Acrobat PDF format. If you have access to a large-format color printer you can print this map yourself from the PDF file. The CD also contains files for use in a geographic information system (GIS). The GIS files were created using ESRI’s ArcGIS 8.2, 8.3, or 9.3 software, depending on the date of creation. ArcGIS coverages as well as interchange files (.e00) are provided for the vector layers, which include the geologic and hydrographic components. Raster images are in TIFF format and include the topographic and cultural-transportation features of the base map. The full written descriptions of the geologic units are provided in a text file format in addition to being on the PDF. Text files can be read by any text reader (such as Notepad, Wordpad, or Microsoft Word). Metadata files (information about the map and how the layers were made) are provided as part of the digital layers and as separate text files. Information about ESRI’s ArcExplorer software is provided on the CD but must be downloaded separately. ArcExplorer is ESRI's free GIS data reader software (for use with coverages, shapefiles, images). Visit the ESRI website at http://www.esri.com/software/arcexplorer/index.html to download the software or get more information about this program

Scale approximately 1:3,000,000 (1 inch to 45 miles). Size 4.5x6 inches;

contact the USGS at http://store.usgs.gov/ .

NOTE:When ordering, please specify quadrangle name, not the number.

If you are interested in the map covering a specific site, you may not be
able to identify the appropriate quadrangle with certainty on this index
map. If you are not sure of the quad name, please contact the MGS Publications
Office for assistance by calling 410-554-5500 or e-mailing
